I have been trying to get 1:1 NAT working like with a Cisco PIX  and for the
most part I use the following rules and it works..but for only a few a hours
then stops.

iptables -t nat -A PREROUTING -p tcp -d 146.145.134.194 --dport 80 -j
DNAT --to 192.168.1.197
iptables -t nat -A POSTROUTING -p tcp -s 192.168.1.97 -j SNAT --to
146.145.134.194

So it works for a few hours then stops, but I can get it working again by
aliasing an interface i.e ifconfig eth0:1 146.145.134.194 bcast and netmask
etc..
And instantly it starts working again. Anyone know what my problem is?
Thanks to all those who helped me out.
